R6 custom resolution?

[waghelsg]

I see that someone has already created bin files for widescreen resolutions to tom clancy rainbow six vegas which is great. But I run a nvidia 7600 through a panasonic high def tv via hdmi cables and my resolution is 1176x664 to correct for overscan problems. I'm sort of new at this so does anyone know how to change the bin files I downloaded from WSGF to support this unique resolution? Any help would be greatly appreciated!
